      One study doesn't end all discussions but I'll take one shoe-leather epidemiology work like it over all the slick computer-generated simulations. This isn't vaporware, it's real. One restaurant, one asymptomatic person, only 11 in line of A/C out of 93 infected. Real data for us.

      Sadly, I don't think we can safely open indoor restaurants. The good news is one asymptomatic person did *not* infect 81 people in that restaurant. The bad news is *one* asymptomatic person infected ten people in line of air flow. No fever, can't screen.https://twitter.com/LadyBrienne1/status/1251853128498057218?s=20 …

      Yes masks can prevent transmission but how can that help in a restaurant where you can’t eat or drink with one on?

      People asking me questions: Study above strengthens case for masks. I try to read key papers. Still many unknowns. PERSONALLY, (not advice, just me!) I try to avoid spending time indoors with others. I feel increasingly comfortable outdoors. I wash my hands after opening boxes.

      We now know *for sure* mass transmission is possible indoors even without coughing/sneezing (pre/asymptomatic). We should all wear masks. I'm not yet seeing many cases of outdoors/surfaces but we should STILL be careful while we wait for studies. Absence of evidence isn't proof.

      Also, please note that coughing/sneezing are game changers to the distances we have all been told—especially sneezing—and that's another big reason to recommend universal masks, especially indoors. Many unknowns remain but this we know for sure: CROWDED INDOORS ARE HIGH RISK.

      Georgia is considering opening retail, restaurants, nail salons, in-person worship and other indoor places next week. Please feel free to share the study on top of this thread with your friends there: one asymptomatic person in a restaurant infected 10.https://twitter.com/JustinGrayWSB/status/1252330712092590080 …

      Check this example flagged by @jeremyphoward in his super useful FAQ on masks. *94* out of 97 cases in a building worked on the same floor! It really suggests transmission through air is much more important than surfaces like elevator/doorknobs. Mask up! https://www.fast.ai/2020/04/20/skeptics-masks/ …pic.twitter.com/XVF9WeJbig

      Can't believe this gets published by the BBC, this late! If you're worried masks can be contaminated by other people's cough and sneezes, what do you think happens to YOUR MOUTH AND NOSE IF you aren't wearing a mask? The other two also make no sense.🙄 https://www.bbc.com/news/health-51205344 …pic.twitter.com/PaPnE1490S

      Tired to see the argument, I created the chart to show the impact. It's like a huge experiment at the cost of thousands British lives. So sad. Wearing mask is essential now and after we lift the lock down, finger cross.pic.twitter.com/YFi0FrmcTN

      That is a very sad experiment, indeed. You should consider publishing that somewhere/anywhere with link to sources.

          You should publish that on Github with a script to regenerate the plot from sources (or as a Google Sheet). Someone could then do a v2 with curves from every other mask on/off country. It’s aggregate observational data but causal mechanism is plausible.

          I agree! This is something good to keep track of. It's not conclusive but country after country... It's a strong signal.
